GCGR antagonist 2, a Furan-2-carbohydrazide, is an orally active glucagon receptor antagonist. GCGR antagonist 2 binds to hGluR with an Kd value of 2.3 nM, and inhibits rat receptor with an IC50 value of 0.43 nM. GCGR antagonist 2 inhibits glucagon-stimulated glycogenolysis[1][2].
GCGR antagonist 2 (compound 74) (25 nM, 250 nM, and 2500 nM; 70 min) inhibits 5 nM glucagon-induced glycogenolysis in primary rat hepatocytes, with an IC50 value of 160 nM[1].
GCGR antagonist 2 (25 nM, 250 nM, and 2500 nM; 60 min) inhibits glucagon-stimulated cAMP level with the recombinant human glucagon receptor in BHK cells[1].
GCGR antagonist 2 (1 nM, 10 nM, and 100 nM; 60 min) inhibits glucagon-stimulated cAMP level with isolated rat liver glucagon receptor in BHK cells[1].
GCGR antagonist 2 (0.5 mg/kg for IV, or 2 mg/kg for PO; single dose) shows mean half-lives of 1.11 h and 1.40 h, respectively[1].
GCGR antagonist 2 (0 mg/kg, 3 mg/kg, and 10 mg/kg; p.o.) at least partly, inhibits the action of the endogenous glucagon responsible for maintenance of euglycemia in glucagon-challenged Sprague-Dawley rats[1].
